Electrocardiograph Recording

S.O.P. No. 9 Version 1.0

1. Introduction The Electrocardiograph obtains a tracing or measurement of electrical conduction which controls contraction of the myocardium (heart muscle). It can aid in diagnosis of a number of cardiac conditions including ischemia, hypertrophy, previous or current infarction and rhythm abnormalities.

2. Objectives To describe the procedure for obtaining an electrocardiograph on patients and promote uniformity within the SDRN in accordance with ICH GCP guidelines.

3. Responsibilities Research nurses trained in the measurement of ECG using equipment supplied and in accordance with ICH GCP guidelines. The Research Nurse should consider if a chaperone is required for this procedure.

Ask if the patient has had an ECG before and if not explain the procedure in terms that they will understand. In particular ensure they are aware that the ECG takes a tracing of the heart and does not involve the use of electricity. If the patient has previously had one performed then ask if he/she would like a reminder. Keep the explanation short.



If appropriate at this point ask female participants if they prefer a female member of staff to carry out the procedure.



Ask the patient to loosen or remove shirts or blouses to allow access to the chest. Women may keep their bra on if they prefer. They should also remove shoes socks tights or stockings. They should lie comfortably on the bed/couch at an angle of approximately 45° (or head on two pillows).
